Plant growth regulators (PGRs) are a tool used to manipulate vegetative and reproductive growth, flowering, and fruit growth and development. PGRs have been successfully used in agriculture for decades to amend plant growth characteristics to maximize yield and grower profit. This new 4-page fact sheet discusses auxins, gibberellins, cytokinins, abscisic acid, ethylene, new classes of plant hormones, use of PGRs for HLB-affected trees, and general considerations for PGR use in Florida citrus groves.

Canopy Management of Citrus Trees

Tree canopy and bearing volume are two important factors in fruit production and fruit quality; generally, trees with larger canopy volumes produce more fruit than smaller-canopy trees. Therefore, canopy management is an important aspect of citrus production in Florida to avoid problems associated with overcrowding and excessively tall trees. This three-page document describes canopy management practices for citrus growers. Written by Tripti Vashisth, Mongi Zekri, and Fernando Alferez and published by the UF/IFAS Horticultural Sciences Department, October 2017.

Citrus Production Guide: Rootstock and Scion Selection

Oranges on trees in a grove at the Citrus Research and Education Center. Photo taken on 03/04/16.When preparing for replanting, an important factor to consider is the choice of rootstock. Choosing the right rootstock and scion combination can result in higher economic returns without any additional cost. Rootstocks affect scion vigor, yield, fruit size, juice quality, and pest tolerance. However, tree growth, yield, and fruit quality interact strongly with climate, soil type, tree spacing, and other factors, often producing contradictory reports on rootstock performance in different areas. This 3-page fact sheet discusses soil characteristics, rootstock effects on pests and diseases, tree spacing and size, and rootstock/scion combination.

2017-2018 Florida Citrus Production Guide: Fresh Fruit Pesticide Residue Limits

Grapefruit.

Current citrus production practices often include the use of various chemicals, many of which are pesticides. Chemical residues on the fruit after harvest are a concern to regulators and the public alike because of their potential negative health effects. Therefore, the US and other countries set maximum residue limits (MRLs) on fresh produce for various chemicals. This five-page document is part of the 2017-2018 Florida Citrus Production Guide and discusses the MRLs for various chemicals used on Florida citrus. Written by Mark Ritenour and published by UF’s Horticultural Sciences Department, October 2017.

Fertigation for Citrus Trees

Microirrigation is an important component of citrus production systems in Florida. For citrus trees, microirrigation is more desirable than other irrigation methods for several reasons: water conservation, fertilizer management efficiency, and freeze protection. Research has shown that when microirrigation systems are properly managed, water savings can amount to as much as 80% compared with subirrigation and 50% compared with overhead sprinkler irrigation. Research has also shown the important advantage of microsprinklers for freeze protection of citrus. This 4-page fact sheet discusses fertilizer solubility and some common fertigation materials. It also offers a fertigation summary.

Citrus Under Protective Screen (CUPS) Production Systems

Citrus can be grown under protective screen structures for fresh fruit production in order to completely exclude the Asian citrus psyllid and therefore huanglongbing disease (HLB, citrus greening). The benefits of eliminating HLB are immediate and include rapid, normal tree growth, higher yields of quality fruit, negligible fruit drop, and uncomplicated fertilizer and irrigation requirements. Because CUPS is a relatively new citrus production system with new challenges, current guidelines are preliminary and undergoing constant refinement through research. This summary of concepts, progress, and tentative recommendations from the first three years of CUPS research in Florida written by A. W. Schumann, A. Singerman, A. L. Wright, and R. S. Ferrarezi and published by the Horticultural Sciences Department was condensed from a comprehensive CUPS Quick Start Guide that will be published and updated on the UF/IFAS EDIS website.
